Lighting Issues with imported rooms

Link to editor: [PlayCanvas | HTML5 Game Engine]
Model viewer:
Model Viewer
I’m in the process of creating a game; however, the problem is anytime I import an asset like a room into my game, its pitch black and I can’t see anything. I can open the model viewer and its perfect but the second I place it in the editor the lighting disappears. Any help is appreciated.
Thank you for your time,
Bradley

Maybe add a lighting entity inside the model or make one outside pointing to your model. Also, I would love to open up your project and help out more in-detail but I think your project size is way too big for my laptop to handle. I’ll try it out with my PC tomorrow or later this week.
